SEAT OR SADDLE SUPPORT IN CYCLES.

SPECIFICATION forming part of Letters Patent No. 632,564, dated September 5, 1899.

Application filed April 28, 1898. Serial No. 679,112. (No model.)

To all whom, it ntay concern:

Be it known that I, PAUL RICHARD G ULDEN, a subject of the King of Saxony, and a resi-. dent of Leipsic, in the Kingdom of Saxony and German Empire, have invented a certain new and useful Improvement in Seat or Saddle Supports in Cycles, of which the following is a specification.

This invention relates to improvements in seat or saddle supports in cycles, (bicycles, tricycles, and the like and its objectis to provide improved means for so mounting the seats or saddles in cycle-frames as to allow' the same to freely follow or yield to the move-- ments of the rider, to thereby neutralize the effects of friction and shocks, and thus to render the exercise of riding more convenient and less fatiguing for the rider.

Bicycle seats or saddles have heretofore in some cases been constructed with relatively movable resilient or elastic parts and in other cases they have been so mounted in the cycleframes as to be suspended and to swing thereon. Cycle saddles or seats of this class do not, however, appear to have been adopted to any great extent, and as regards the sus-' pended swinging saddles they present several objections. They cannot be applied to all bicycles, but only to such as have been specially constructed or arranged for the purpose, and, on the other hand, they present this objection, that they do not afiord a sufficient counter-support for the rider when he wants to put extra pressure onto the pedals, as in racing or riding uphill. According to my present invention I avoid these objections by providing improved means whereby the seat or saddle may be so mounted on a cycle as to be freely movable thereon both longitudinally and laterally on its axis, but wherein the extent of such movements, and more especially the extent of its rearward movement, is confined within certain fixed limits, so that the rider no matter what pressure he applies in pedaling will have a fixed counter-support.

My invention therefore consists in a seat or saddle support for cycles having a movable part constructed and arranged as hereinafter more fully described and shown in the accompanying drawings, the said seat or saddle support possessing the additional advantage thatit maybe readily applied to any of the usualcycles and that cycle seats or saddles .of the usual kinds may be attached thereto.

In the accompanyingdrawings, illustrating my invention, by way of example, Figure 1 is;

a side elevation, partly in vertical longitudinal section, of my improved seat or saddle support, the same being here showrras mounted in the respective tubular portion of a bicycle or other frame and its attached saddle being indicated by dotted lines. I Fig. 2 is a corresponding vertical transverse section on the line 00 w of Fig. 1. Fig. 3 is a similar section of a modification to be referred to.

The improved seat or saddle support, as shown in Figs. 1 and 2, consists, essentially, of a tubular casing A, provided with-the usual shank B for insertion into the tubular frame portion 0 of a bicycle, tricycle, or other similar vehicle, and of a slide E, supported within the said casing A on antifriction-balls D, so as to be capable of both a longitudinal sliding movement and of a lateral rocking movement to the right and left within the said casing. An arm F, provided on top of the said slide E, extends upward through a longitudinal guide-slot G of the casing A and carries at its upper end a bar H, to which the seat or saddle may be attached in the usual and well-known manner. The curvature of the upper surface of the slide E preferably corresponds with that of the adjoining inner portion of the casing A, while the curvature of its lower surface conforms to the outer curvature of the supporting antifriction-balls D. This arrangement allows free movement of the slide E, and hence of the attached seat or saddle, both toward the front and rear, as well as to the right and left, as indicated in the drawings, the amount of friction being at the same time reduced to a minimum. The extent of the lateral rocking movement is limited, on the one hand, by the engagement of the arm F with the respective sides of the guide-slot G and, on the other hand, by the engagement of the edges of the slide E with the shoulders H,provided within the casingA, as shown, whereas the forward and rearward movement of the said slide is limited by the respective closed ends of the casing A. Within the latter cushions or pads J, of india-rubher or other suitable material, may be provided for the ends of the slideE to act against,

the said cushions or pads being preferably held in place by threaded caps K, screwed on to the respective threaded end portions of the casing, the said caps thus closing the ends of the casing. It is obvious that for closing the ends of the casing I may also employ screw-threaded plugs entering corresponding threaded openings in the respective casing ends, or that other suitable means may be employed for the purpose.

In order to provide for removing the. slide .E from within the casing A, theone upper end portion of the latter adjoining the respective end of the guide slot G may be formed as a separate movable part adapted to slide in suitable guides, as shown at L in Fig. 1, and to be partly or entirely withdrawn. I may also surround this end portion of the casing with suitable rings to assist in normay be attached at or near one of the ends of the casing, so as to thereby give the entire seat or saddle support an L. shape instead of the T shape shown. I also wish it understood that it would not be a departure from this invention tosubstitute antifriction -rollers for the antifriction-balls shown. Having now described my invention, what V I claim as new, and desire to secure by Letters s Patent, is 1. In a cycle seat or saddle support having a tubular casing formed on the saddle post, a sliding and rocking body mounted in the casing and supported by antifriction-bodies an arm on said sliding'and rocking body ex--:"" tendingthrough a slot-in theupper side of said casing and being adapted for the recepj tion of thesaddle in the ordinary manner, substantially as herein described. 1 f 2. In a'cycle seat or saddlesupportythe;P combination,with a tubular casing A having an upper guide-slot G and a shank B, of 1 56 sliding and rocking body E supported within said casing by antifriction-bodies D, an arm F on said sliding body projecting through said guide-slot and having the usual extene sion H for the attachment of the seat or sad [55 die, and stops .I and H for limiting the axial a and rocking movement respectively of the sliding body, substantially asset forth.

In witness whereof I have hereunto set my hand in presence of two witnesses. Y PAUL RICHARD GULDEL.
